Adaptive density control in heterogeneous wireless sensor networks with and without power management

Machado, R.; Ansari, N.; Wang, G.; Tekinay, Şirin (IEEE, 2010-04-30)

The authors study the design of heterogeneous two-tier wireless sensor networks (WSNs), where one tier of nodes is more robust and computationally intensive than the other tier. The authors find the ratios of densities of ...
Coverage properties of clustered wireless sensor networks

Machado, R.; Zhang, W.; Wang, G.; Tekinay, Şirin (ACM, 2010-08)

This article studies clustered wireless sensor networks (WSNs), a realistic topology resulting from common deploymentmethods.We study coverage in naturally clustered networks of wireless sensor nodes, as opposed to WSNs ...
Diffusion-based approach to deploying wireless sensor networks

Machado, R.; Tekinay, Şirin; Zhang, W.; Wang, G. (Inderscience, 2010)

An important objective of Wireless Sensor Networks (WSNs) is to reliably sense data about the environment in which they are deployed. Reliability in WSNs has been widely studied in terms of providing reliable routing ...
Redundancy estimation and adaptive density control inwireless sensor networks

Machado, R.; He, H.; Wang, G.; Tekinay, Şirin (Old City Publishing, 2010)

While dense random deployment satisfies coverage and sensing requirements, constructing dense networks of sensor nodes poses the problems of obtaining node location information.We provide an analytical framework for ...
